Adam Savage knows a thing to two about using tools, and over the years he's tried all kinds of belt holsters for his multi-tool with no success. So, he built his own, and in a video over at Tested, he shows off how.

The holster is made out of a piece of metal and is cut so he can quickly get his multi-tool (a Leatherman Wave, if you're curious) out of his belt without messing around with leather clips. The build process itself is interesting to watch and you'll learn all kinds of things about general metalworking along the way.
